Brake parts cleaner is good, but, the best stuff I've found is Castrol Wheel Cleaner, comes in a purple bottle with a silver nozzle. That stuff is so bad assed. I suggest a good stiff bristled brush for the heavier deposits, but, it'll get most of the crap off with no scrubbing. The brush at the car wash will not get the deposits off, you'll have to buy one.
